The gain can be an increase in readability.  For instance, being able to
use δx or ΔT as variables (e.g. in Julia) instead of delta_x, delta_T or
similar.  Mathematical expressions become more like the actual
mathematics.  Julia, in particular, actually uses unicode characters for
some of the operations, such as

for i ϵ 1:10

although you can still write

for i in 1:10

if you need to.

And you might be able to imagine being able to define operators such as
· and × for vector arithmetic.

Etc.  US-ASCII is very limiting for expression.

Just my 2¢. 😉
